To all whom it may concern I Be it known that I, EDWIN R. Pnonnn'r,

, ment in Metal Window Frames and Sashes,

of which the following is a specification.

This invention relates to windows and frames made of sheet-metal bent orshaped so as to provide hollow insulator air-chambers wherever possibleand of a type whose object is to provide for lateral ad'ustabilit of thesash run-Ways in thesi e jambs of the frame to compensate for theexpansion and contraction of the material-andof the building-structureisshown inthese views in single-line, (118;

for the settlin to meet fire, wind, dust, and water resistin orretardant requirements. g

in; description of the objects of the invention herein is such as-to bereadily um. derstood as they are interwoven or interspersed with thedetailed description of the parts of the device that are clearly shownin the accompanying severalsheets of drawingrs, in which,

lgure 1 1s a horizontal-section taken on the dotted-line a, a, of Fig.2, but showing the customary two sashes, however, broken es and withtheir lower framebars in plan,

and, also, with the upper-sash as though at the bottom of the frame,although its adjacent balancing-weight is down in the position itoccupies when said upper sash is in its normally-closed position, as inFig.

2; Fig. 2, an outside elevation of the entire window, showing noparticular details; Fig. 3, a detached horizontal-section of mycompensating, auxiliary, adjustable, side runway strip that is shown inFig. 1 and taken "on a line either above or below that of Fig.

2; Fig. 4, a detail elevation of one of the adjusting-screws for theauxiliary run-way strip seen in Fig. 1, but with its lock-nut separatedtherefrom; Fig. 5, an inside-elevation of the window, omitting thelowersash and showing one of the upright-sides= of the frame broken awayat its lower portion to display the weight at that side for theclosed-position of the upper-sash, the removable cap-plate in the weightman-hole, and showing the upper end of said uprightside broken away todisclose the ready ma11- ner of mounting a sheave or pulley for theweight-rope; Fig. 6, a vertical, sectionalelevation taken on theperpendicular dottedline b, b, of Fi 5, but including both sashestherein an both in raised-positions, and. with the cap-plate removedfrom its weight hand-hole at the bottom of the runway used by theupper-sash and the latter being shown as partly lowered; Fig. 7, ahorizontal section, similar to Fig. 1, but on a smaller scale, and takenon the dottedline 0, c, of Fig. 6, omitting the sashes; Fig. 8, ahorizontal, detail section of the removed weight cap-plate of Fig. 6,and Fig. 9, a vertical, detail secti' nal-elevation of the saidcap-plate seen in ig. 8.

It will be observed that the sheet-metal gramform instead of using,cross-section lines md it willjof course, be understood that wherespaces occur: between some of the surfaces the. latter should be inactual contact and especially in parts that interlock or fold and snuglyfit one within the other, although where parts slide they should bepractically contiguous but free to reciprocate without unduefrictional-contact.

1 indicates the sill; 2 and 3 the upright side-members; and 4 thetop-member or head of the frame of the window, allmade of sheet-metalbent into the desired shapes and in hollow, or in insuiator air-chamberform wherever possible and feasible.

Each of the two hollow uprights 2 and 3 is composed of a metal sheetwhose opposite vertical longitudinal edges 5 and 5, are separated at therear of the uprights and then formed into inwardly-turned, almostlapping or closed hooks that angle at 6. The metalfrom hooked-edge 5then takes a straight course 7 forward; then angles at 8;

then a short straight lateral outward course 9; then angles at 10; thentakes another straight course 11 forwardly to an angle 12; then takes astraight course 13 inwardly, at

the outer end of" which a U-shape bend is made at 14 to form a narrowvertical slit or groove 15; then takes another straight course rearwardcourseii is taken to an angle 23 that leads to a. short, centraltransverse. course or ligament 2% that thence angles at Q? and advancesforwardly in a straightline 26 (corresponding tothe part. that itparallels and alines) until a r-angle 27 is reached 35 with anothershort lateral, outward straight zeourse -flfi till reaching an angle 37,whenceanother st'raightrearward course 38 is taken to wrangle- .39(corresponding to the angle 1 0 and another short inwardlylatrralstraighteonrse 40.

Thus any'slight orother variations in the fitting of the sashes in the channel ran-wayscan be readily adjusted to-a nicety, looking always howerer to the treeand easy slidin'ganm'ements of said sashes in opening; and closing thewindow, and with a view to provide a proper closure or barrier againstthe entrance of fire, smoke, dust, wind and water into thebuilding-structure.

The window-sashes are both made alike along their opposite verticaledges or side stiles as well shown in Fig. 1, in which A indicates thelowersash and I) the upper one. Their frames are of hollowed, sheetmetalstructure and they are provided with slightly tapered or spreadinggrooves, as shown. at C, for the glassdights D, whereby the use of puttyor cementcan be made against entrance of tire and other objectionableelements from without along those lines. 'The vertical edges of thesashes are formed of metal sheets whose opposite vertical edges at bothcorners are bent into double-hooks E, and fillers or bridgepieces F areprovided that have opposite out wardly-disposed hook-edges G adapted tointerlock with the said double-hook corners E of the vertical edges ofthe sashes. These hook-members are, of course, closed or brought tightlytogether to assure proper joints free from leakage of any kind, and theyare strong and still for use in guiding the sashes in the adjustablechannel runways provided in the side-joints of the uprights of theWindow-frame previously described.

A metallic, hollow, coiled head or sidestrip H is provided on the art 13of each of the hollow-uprights, and it has an extension I that cngagesthe slit 15, such extension also projecting laterally at J to form abroad bearing-surface or weather-strip for each of the opposite,extended side-edges or flanges of the inner fare of the sideslides ofthe lower-sash, as best shown in Fig. 1. A seriesof screws K is used inthe side-strips or heads H for fastening them in place on theparts 13and reinforcing bars or backings L are also used on the inner faces ofsaid parts 13 to receive the inner threaded-ends of said screws and themthe desired hearing.

A deep, hearing, channeled run-way sur face is provided for the verticalside-extensions on the inner corners of the side'stiles of the sashes,especially along the vertical center or parting-strip of the uprights 2and 3 of the frame. the parts or members 48. 49 and 51 forming constantguide-ways that prove effective for the desired free slidinn-engagementof the adjacent side-extensions or flanges of the two sashes that arenot a ti'ected by. (inpansion or contraction nor by the settling of thebuilding-structure after the window has been installed for use. Theadjustment of the run-way guard-fillers to and from the side-stiles ofthe sashes corresponds to the variations that occur in the relations ofsaid side-stiles to the said rum way fillers. consequent on saidcontraction,

expansion and settling, the rear extensions or guards-proper formed bythe parts 50 of the auXiliar ,'-tiller being the essential ones of myinvention herein 10 till and compen sate for any space or gaps incurredby the said rpansion. eontractioi'i or settling coin nion to Wooden andnwtal windo\\'-structures alike and rerulering them greatly defectivel'or use.

The channel run-ways: are continuous and of one piece oi material fromtop to bottom, so that there is no ohstrurtiou whatever to the free andsmooth sliding or perfect runuingr of the sashes at all times. Thebalancingnvcights M and N are readily placed in their properrmr-ehanihers through the openings provided at the lower ends of thejamhs at eith r side of the runavay and shown in Fig-s. 7;, G and T, andwithout removing either sash, and the rear-extensions of the pockets forthe channeled runways lie between the weights to form con tinuouspar-tings that prevent the twisting and clogging of the weights.Cappinglat -s P are used in the weight manholes if). as shown in de allin Figs. 8 and 9, and, also. in place in Fig :3. tand 7, such plateshaving sideiiannezs that extend through said openin (l, and oppositeend-extensions p p, the latter having holes 7) for the insertion ofcountersunk screws 77 whose inner threaclm'iends engage the reinforcinghearing-plates [2* on the inner faces of the joints.

A pendent crater-formation Q extends from the lower inner edge of thelower-sash A for over-lamung-engagement with an overlappin or und rcutsill formation or projection as best seen in Fig. 6, but does notcontact with the sill, to avoid entrance of tire, draft and otherobjectionable ele ments along said lower edge or bottom of thelowersash.

Interlocking l hook-formations S and T are provided on the meeting-railsof the tvvo sashes to guard against the entrance of fire and otherobjectionable elements at that point in the window-strueture.

The ushal sash-cord pulleys U are mounted in the'tops of the uprights '2and 3, as seen in Fig, 5. wherein the pulleys may be easily replaced,should it become necessary to do so, and it is furtherheeessary to takeeither sash out or" the frame to insert or remove the heights,

in the use of my invention herein there absolutely no reason. for ordanger of the sashes sticking or getting too tight in the run-ways. andthe adjustable runway slides with their rear guard-extensions can neverfail to prevent the entrance of fire. and other like objertionaoleelements from without. Any one can easily perform the mljustment oi thrain-way slides. and it will not be necessary at any time to plane orotherwise remove any of the side-surfaces of the sidestiles whatever onaccount of varying widths of sashes used.

I claim In a sheet-metal window-structure, slidable sashes each havinglaterally-extending tongues, provided along its opposite side-stiles,hollow upright side-frames each having a central, vertical chamber orchannel that has an inwardl bent or reduced rearward extension,independent, vertical, doubly-grooved track-members freely arranged insaid side-frame chambers or channels and adapted to extend therefrom forthe sliding-engagement of said tongues 0n the sash-stiles, telescopic,angular fillermembers having reduced rear-extensions coinciding andengaging with the rear-extensions of the side-frame chambers, U-

shape guard-fillers extending rearwardly from the track-members withinsaid chambers and their rear-extensions, and means comprising a seriesof horizontal collaredscrews and pierced vertical bars adapted forengagement by said screws to adjustablysupport the said track-membersand their filler-members in said chambers whereby the said guard-fillersand track-members may be moved laterally to and from the tongued edgesof the sash-stiles to compensate for wear and to allow for varied Widthsof sashes in properly fitting and operating them in the Window-frame.
